Arduino Unois a microcontroller board based on the ATmega328PIt has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.. You can tinker with your UNO without worring too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again.

"Uno" means one in Italian and was chosen to mark the release of Arduino Software (IDE) 1.0. The Uno board and version 1.0 of Arduino Software (IDE) were the reference versions of Arduino, now evolved to newer releases. The Uno board is the first in a series of USB Arduino boards, and the reference model for the Arduino platform; for an extensive list of current, past or outdated boards see the Arduino index of boards.

TheArduino Leonardois a microcontroller board based on the ATmega32u4 . It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.


The Leonardo differs from all preceding boards in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Leonardo to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port. It also has other implications for the behavior of the board;

Based on Avia Semiconductor's patented technology, HX711 is a precision 24-bit analogto-digital converter (ADC) designed for weigh scales and industrial control applications to interface directly with a bridge sensor. The input multiplexer selects either Channel A or B differential input to the low-noise programmable gain amplifier (PGA). Channel A can be programmed with a gain of 128 or 64, corresponding to a full-scale differential input voltage of +-20mV or +-40mV respectively, when a 5V supply is connected to AVDD analog power supply pin. Channel B has a fixed gain of 32. Onchip power supply regulator eliminates the need for an external supply regulator to provide analog power for the ADC and the sensor. Clock input is flexible. It can be from an external clock source, a crystal, or the on-chip oscillator that does not require any external component. On-chip poweron-reset circuitry simplifies digital interface initialization. There is no programming needed for the internal registers. All controls to the HX711 are through the pins.

Size 43mm * 21mm * 14mm (L * W * H)

This module can take an input voltage of between 5 and 32V DC and converts it to an output voltage between 5 and 35V DC.

You may use this module to generate high voltage upto 32V from small battery packs other power sources.

Features

  • Wide input voltage 3.5V ~ 32V, optimum manufacturer rated operating voltage range is 5 ~ 32V;
  • Wide Output voltage 5V ~ 35V;
  • Built-4A efficient MOSFET switches enable efficiency up to 94%; (LM2577 current is 3A)
  • High switching frequency 400KHz, can use a small-capacity filter capacitors that can achieve very good results, the ripple smaller and smaller. (LM2577 frequency only 50KHz)
Test Results
  • Input 3V Output 12V 0.4A 4.8W (input voltage less than 5V not recommended)
  • Input 5V Output 12V 0.8A 9.6W
  • Input 7.4V Output 12V 1.5A 18W
  • Input 12V Output 15V 2A 30W
  • Input 12V Output 16V 2A 32W
  • Input 12V Output 18V 1.6A 28.8W
  • Input 12V Output 19V 1.5A 28.5W
  • Input 12V Output 24V 1 A 24W

Technical Parameters
  • Module Properties Non-isolated boost (BOOST)
  • Rectification Non-Synchronous Rectification
  • Input Voltage Range 5V ~ 32V
  • Output Voltage RAnge 5V ~ 35V (Note If you want to get the max voltage, you should make the input current as least 3A)
  • Input Current 4A (max), no-load 18mA (5V input, 8V output, no-load is less than 18mA. Higher the voltage, the greater the load current.)
  • Conversion efficiency <94% (greater the pressure, the lower the efficiency)
  • Switching frequency 400KHz
  • Output Ripple 50mV (the higher the voltage, the greater the current, the greater the ripple)
  • Load Regulation +- 0.5%
  • Voltage Regulation +- 0.5%
  • Operating Temperature -40 ~ +85
  • Dimensions 43mm * 21mm * 14mm (L * W * H)
When using these modules remember that the output current will be a lot less than the input current, (remember - W = VA). For example, if you have a 10V output at 1A from a 5V input, the input current will be around 3.6A. The real-life maximum amount of power you can get out of these things is around 10W.

If Output current is greater than 2.5A (or output power greater than 10W) use with heatsink only.

  • You could download the driver of Elegoo Nano V3.0 at: http://bit.ly/2pMF4in
  • The Nano is using the chips ATmega328P and CH340, not FT232 as official Arduino, so pls. use the driver from above link.
  • It is a smallest, complete, and breadboard friendly board. It has everything that Diecimila/Duemilanove has (electrically) with more analog input pins and onboard +5V AREF jumper.
  • Nano's got the breadboard-ability of the Boarduino and the Mini+USB with smaller footprint than either, so users have more breadboard space. It's got a pin layout that works well with the Mini or the Basic Stamp (TX, RX, ATN, GND on one top, power and ground on the other).
  • The Nano can be powered via the Mini-B USB connection, 6-20V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27). The power source is automatically selected to the highest voltage source.
